Qr code analyzer

Abstract

A method for analyzing QR codes. The method utilizes a sandbox environment to test resources linked by the QR code. The method tests each linked resource while proceeding through the redirection chain. The method determines whether each resource in the chain contains threats. The method determines an overall safety rating for the QR code based on testing each resource in the redirection chain. The method presents the redirection chain and the safety rating to a user.
